Every evening, the nurse anesthetist Cheryl Shadden lies awake in her residence in Granbury, Texas, listening to a nonstop roar. “It’s like sitting on the runway of an airport the place jets are taking off, one after one other,” she says. “You may’t even stroll out in your again patio and communicate to any person 5 ft away and have them hear you in any respect.”
The noise comes from a close-by bitcoin mining operation, which arrange store at a energy plant in Granbury final yr. Since then, residents within the surrounding space have complained to public officers about an incessant din that they are saying retains them awake, offers them migraines, and seemingly has precipitated wildlife to flee the area. “My residents are struggling,” says Hood County Constable John Shirley.
Granbury is certainly one of many cities throughout the U.S. feeling the adverse impacts of bitcoin mining, an energy-intensive course of that powers and protects the cryptocurrency. These impacts embody carbon and noise air pollution, and elevated prices on customers’ utility payments. Based on the New York Occasions, there are 34 giant scale bitcoin mines throughout the U.S. In 2022, the crypto market tumbled, partially because of high-profile collapses of crypto corporations like Sam Bankman-Fried’s FTX. However in 2023, costs rebounded as soon as once more, and mining corporations determined to increase their operations as a way to money in, inflicting world vitality consumption for mining to double, in accordance with one research. Critics say that mining is inflicting each long-term environmental injury, because of its vitality use, in addition to native hurt. “We’re at a loss right here,” Granbury resident Shadden says. “We would like our lives again.”
Bitcoin is so energy-intensive as a result of it depends on a course of often known as proof-of-work. Quite than being overseen by a single watchdog, bitcoin is designed to disperse the accountability of the community’s integrity to voluntary “miners” across the globe, who forestall tampering by means of a posh cryptographic course of that consumes an enormous quantity of vitality. Over the previous couple of years, Texas has develop into a world chief in crypto mining as a result of miners can entry low cost vitality and land there, in addition to profit from pleasant tax legal guidelines and regulation. Bitcoin miners eat about 2,100 megawatts of the state’s energy provides, and firms like Riot Platforms and Marathon Digital Holdings have just lately expanded within the state. (Different states, conversely, have pushed again on the {industry}: In 2022, New York imposed a moratorium on bitcoin mining over considerations that miners have been overusing renewable vitality assets.)

In December, Marathon paid $178 million to buy bitcoin mines in Kearney, Nebraska and Granbury from Generate Capital. However with the Granbury buy, Marathon additionally inherited a swath of indignant close by residents throughout Hood County whose lives have been upended by the mining facility. Generate Capital began working the 300-megawatt facility, which sits about an hour southwest of Fort Value, in 2023. Initially, many residents have been unaware what, precisely, was inflicting the noise. Shannon Wolf, who lives about 8 miles from the plant, first assumed that the rumble was coming from a close-by practice. “It has woken me from a lifeless sleep earlier than,” she says.
The rumble, it turned out, comes from the huge cooling followers that the power runs to maintain their computer systems from overheating. Knowledge facilities, like bitcoin mines, additionally run huge cooling followers which have drawn the ire of close by residents.
As residents realized what had precipitated the din, social media platforms like NextDoor and Fb flooded with complaints. “This sound has been driving me to the purpose of madness. I’ve steady migraines, I can barely get out of my head, vomiting, nosebleeds, painful knots on my scalp,” wrote one commenter. “All of the birds have left, solely [buzzards],” wrote one other poster.
As complaints swelled, native officers introduced their considerations to the location’s operator, US Bitcoin Corp. Over the summer season, the corporate agreed to assemble a 24-foot sound barrier wall on one finish of the property at the price of $1 to $2 million. However whereas the wall decreased sound in some areas, it truly amplified it in others. “To be trustworthy, the complaints have gotten louder for us for the reason that mitigation efforts,” Constable John Shirley says.
Shirley says that he’s monitoring the decibel ranges of the power. Texas state legislation stipulates {that a} noise is taken into account unreasonable if it exceeds 85 decibels. For comparability, vacuum cleaners usually run at round 75 decibels—and a heart specialist informed TIME in 2018 that continual publicity to something over 60 decibels had the potential to do hurt to the cardiovascular system. Shadden took her personal readings at her home close to the Bitcoin mining facility that reached 103 decibels.
However the most penalty for breaking that Texas legislation is a $500 effective, Shirley says, including: “The state legislation is insufficient.” He says that he has been speaking to the county lawyer’s workplace about choices for recourse. “If we have now a repeated violation drawback, he might be trying into potential injunctive aid,” he says.
The neighborhood’s ire boiled over at a city corridor on Jan. 29, hosted by Shirley and Hood County Commissioner Nannette Samuelson. About 75 folks stuffed the room to complain in regards to the facility. Complaints from attendees included migraines that required journeys to the emergency room and a vertigo prognosis. One attendee mentioned she had been pressured to place her chihuahua on seizure remedy. Others claimed that their home windows rattled from the vibrations, and that the noise made their houses unsellable.
“How does Hood County profit from having such a ridiculous factor?” requested one girl. “What does this neighborhood acquire from having them there?”
Charlie Schumacher, the vp of company communications at Marathon Digital Holdings, wrote in an e-mail to TIME that the corporate was unaware of the noise points when it bought the location. He mentioned Marathon was commissioning a 3rd occasion to conduct a sound research as early as subsequent week.
“Marathon deeply values {our relationships} with the communities wherein we dwell and work, and we respect the candid enter our neighbors have shared with us in latest weeks,” he wrote. “We’re at present gathering info. If there’s a drawback that we will affect, then we’ll do all the pieces we will to handle it.”
US Bitcoin Corp didn’t instantly reply to a request for remark.
Whereas the fixed noise has develop into a serious irritant within the county, residents additionally fear in regards to the facility’s influence on their energy provide and the encircling atmosphere. Texas has a notoriously fragile grid that turns into strained in chilly climate: a 2021 deep freeze precipitated tens of millions of individuals to lose energy. Wolf Hole, the fuel plant that provides the Granbury bitcoin mine with vitality, failed throughout each that disaster and the 2011 storm. (The plant modified possession in between the 2 storms.)
This yr, components of Texas have been hit with a frigid arctic entrance in mid-January, with temperatures dropping into the kids. The state’s grid operator, ERCOT (Electrical Reliability Council of Texas), requested Texans to preserve electrical energy. The grid principally held up underneath pressure, and Wolf Hole continued to function at full capability, as did the mining operation.
Nonetheless, some residents in rural Hood County misplaced energy. That included Hunter Sims, who lives a mile and a half from the plant and misplaced energy for 9 hours, counting on a backup generator for his properly. Sims was angered that he was with out energy whereas the mining operation continued unabated. Total, he says his high quality of life has worsened because of the facility’s noise air pollution. “After I’m sitting in my lounge, I can hear a loud buzzing,” he says. “You may’t actually calm down.”
A consultant for Constellation Power, the corporate that runs Wolf Hole, mentioned that any energy outages weren’t a results of any points on the plant, however slightly on the native stage of transmission or distribution.

Erik Kojola, a senior Local weather Analysis Specialist for Greenpeace USA, says he’s monitored comparable complaints from residents close to new bitcoin mining facilities throughout the nation, in Iowa, Indiana, Nebraska, and upstate New York. He additionally contends that bitcoin mining poses a a lot bigger menace to the atmosphere. “Bitcoin mining is actually a lifeline for fossil fuels,” he says. “It is finally creating a brand new industrial scale demand for vitality at a time the place we have to be decreasing our vitality use.”
Again in Granbury, the discomfort attributable to the plant is inflicting some consternation for a area that largely prides itself on being pro-industry and anti-regulation. “I agree with folks having the best to personal a enterprise if it’s not unlawful or amoral,” says Granbury resident Wolf. “However if you’re harming a bunch of individuals, there must be some sort of treatment.”
